I also have a problem when zooming or panning the map.
var point = new OpenLayers.Geometry.Point(0,0)
; var pointFeature = new
OpenLayers.Feature.Vector(point,null);
vectorLayer.addFeatures([pointFeature])
;the pointFeature is not always placed on the same place.
I'm using a google base layer and the map projection code is 4326

Subject: How to force a vector layer to use canvas instead of SVG?
Hi,
I'm trying to create a vector layer. My code is quite similar to the source
code in:
http://openlayers.org/dev/examples/select-feature-multilayer.html?renderer=Canvas
However, I notice that the renderer=Canvas (url parameter) is not being used,
because features are created using svg (inspecting with firebug)
Here is my code for the layer creation:
var layer_style = new OpenLayers.StyleMap({
"default": new
OpenLayers.Style(OpenLayers.Util.applyDefaults({fillColor: "red",strokeColor:
"gray",rotation: 45,pointRadius: 15},
OpenLayers.Feature.Vector.style["default"])),
"select": new
OpenLayers.Style(OpenLayers.Util.applyDefaults({graphicName: "square",
rotation: 45, pointRadius: 30}, OpenLayers.Feature.Vector.style["select"]))
})
var vectorLayer = new OpenLayers.Layer.Vector("vLayer", {
styleMap: layer_style,
renderers: ["Canvas"]
})
;map.addLayer(vectorLayer)
;I also notice that the options passed on the vector layer instantiation
apparently don't mach the documentation:
http://dev.openlayers.org/releases/OpenLayers-2.12/doc/apidocs/files/OpenLayers/Layer/Vector-js.html
I'm using FF12, Chrome 22.0.1229.94
Openlayers 2.12
